The Solar Resource

This chapter explains applications and basic principles of solar energy. The theory of diffuse and direct solar radiation, irradiance, and insolation are discussed (as well as the terms kilowatt hours, peak sun hours and langleys). Estimation of energy available at a given site using meteorological records and local knowledge is outlined. Tracking the sun to increase energy output is examined.
